Abstract

Description

최근에는 LCD, OLED등의 평판 디스플레이 관련 기술이 발달하고 있으며, 접었다 펼 수 있는 폴더블 디스플레이 롤 형태로 감을 수 있는 롤러블 디스플레이와 더불어 늘리거나 줄일 수 있으며 자유로운 형태로 변화 가능한 스트레처블 디스플레이 장치에 대한 연구가 활발히 진행되고 있다. 스트레처블 디스플레이를 구현하기 위해서는 먼저 스트레처블 기판 제작에 대한 선행연구가 진행되어야 하며, 주로 PDMS(polydimethylsiloxane), PU(polyurethane)과 같은 소재들로 연구가 진행되고 있다. 최근 어플리케이션에 대한 개발이 다양화되면서 디스플레이에 터치센서를 도입하게 되면서 디스플레이 표면에 대한 내오염 및 내스크래치성의 중요성이 커지고 있다.Recently, technologies related to flat panel displays such as LCD and OLED are developing, and in addition to foldable displays that can be folded and unfolded, rollable displays that can be rolled up in the form of rolls, and stretchable display devices that can be stretched or shortened and freely change into shapes. Research is actively underway. In order to implement a stretchable display, prior research on the production of stretchable substrates must first be conducted, and research is mainly conducted with materials such as PDMS (polydimethylsiloxane) and PU (polyurethane). Recently, as the development of applications has diversified and touch sensors have been introduced to displays, the importance of anti-contamination and scratch resistance for the display surface is increasing.
최근 어플리케이션에 대한 개발이 다양화되면서 디스플레이에 터치센서를 도입하게 되면서 터치에 의한 디스플레이의 오염 혹은 스크래치에 의한 손상이 발생하여 성능이 저하되거나 디스플레이에 영구적인 고장을 일으킬 수 있다는 문제가 있었다. 이에 본 발명자들은 디스플레이 표면에 대한 내오염성 및 내스크래치성을 가진 스트레처블 디스플레이용 연신기판을 개발하고자 예의 연구 노력하였다. 그 결과, 퍼플루오로 폴리머와 연신기판 제조용 폴리머를 혼합하여 코팅을 하면, 두 가지 폴리머의 비중 차이에 의하여 한 번의 코팅으로 2층의 연신기판이 쉽게 제조될 수 있음을 규명함으로써, 본 발명을 완성하게 되었다. Recently, as the development of applications has diversified and touch sensors have been introduced to displays, there has been a problem that the display may be contaminated by touch or damaged by scratches, which may reduce performance or cause permanent damage to the display. Accordingly, the present inventors made extensive research efforts to develop a stretched substrate for a stretchable display that has stain resistance and scratch resistance on the display surface. As a result, the present invention was completed by demonstrating that when a perfluoropolymer and a polymer for manufacturing stretched substrates are mixed and coated, a two-layer stretched substrate can be easily manufactured with a single coating due to the difference in specific gravity of the two polymers. I did it.

두께측정기(Mitutoyo, 547 thickness gauge)로 압력 20±0.2 kPa로 5초 동안 가압한 후 제품의 제조방향으로 처음 300 mm 부분은 잘라내고, 다시 그 끝 부분에서 20 mm 안쪽인 부위에서 양끝으로 각각 나비(폭)의 10% 안쪽으로 들어간 지점 2곳과 그 사이를 9등한 지점 8곳을 합한 10곳을 0.01 mm 까지 두께를 측정하여 그 측정치의 평균치를 구하였다. After pressurizing with a thickness gauge (Mitutoyo, 547 thickness gauge) for 5 seconds at a pressure of 20 ± 0.2 kPa, the first 300 mm part is cut in the manufacturing direction of the product, and then again from the area 20 mm in from the end to both ends. The thickness was measured to 0.01 mm at 10 points, including 2 points within 10% of the width and 8 points between them, and the average of the measurements was obtained.
상기 실험예 1 내지 3의 결과는 표 4에 나타내었다.The results of Experimental Examples 1 to 3 are shown in Table 4.
상기 표 4에 나타낸 바와 같이, 본 발명의 퍼플루오로 폴리머를 포함하는 스트레처블 디스플레이용 연신기판은 물접촉각이 높아져 내오염성 및 내스크래치성이 우수하고, 투과율이 증가하고 헤이즈가 감소하므로 디스플레이로서의 광학적 성능이 우수해짐을 알 수 있다. As shown in Table 4, the stretched substrate for a stretchable display containing the perfluoropolymer of the present invention has an increased water contact angle, has excellent stain resistance and scratch resistance, and has increased transmittance and reduced haze, so it can be used as a display. It can be seen that optical performance is improved.
